Science Daily
"ScienceDaily (Jan. 19, 2010) — Planet Earth has warmed much less than expected during the industrial era based on current best estimates of Earth's "climate sensitivity" -- the amount of global temperature increase expected in response to a given rise in atmospheric concentrations of carbon dioxide (CO2). In a study to be published in the Journal of Climate, a publication of the American Meteorological Society, Stephen Schwartz, of Brookhaven National Laboratory, and colleagues examine the reasons for this discrepancy."
